Burglar Alarms and Home Security

Nothing would give you greater peace of mind than knowing that your privacy and your property would not be violated. Those who are willing to spend fortunes to protect their privacy and property hire security personnel and guard dogs. While other who are not willing to pay the price simply make do by installing strong locks on key entry points to their homes, which often times do not keep away a determined intruder. Today’s burglar alarm systems provide an effective alternative of protecting homes and businesses at reasonable cost.

At the core of modern burglar alarm systems lies a very simple concept—an alarm that goes off once a switch is tripped off by the closing or opening of an electric circuit. These burglar alarm systems vary widely in terms of complexity and cost. The market offers complex hardwired systems that require at least a day of installation of wires and switches by a professional, as well as simple wireless security kits that can quickly be installed by almost anyone who takes the time to read installation instructions that come with the kit.

These burglar alarm systems work best in guarding vital entry points and weak spots such as fences, gates, doors and windows, where intruders are expected to break through. Unfortunately, these are not as effective in protecting the inside premises of a house or building because the movements of an intruder cannot be predicted once inside the premises of a building or a house. Consequently, it would be difficult to determine where the alarm switches would be positioned.

Because of this difficulty in determining the precise placement of switches inside the house premises, motion detectors have been developed that could cover a wider area inside the house. At the heart of these devices are sensors that could detect motion. Radar based burglar alarm systems “catch” reflected microwave or ultrasonic sound waves that they emit, and could detect any change in the reflection pattern brought about by the slightest movement inside the premises. Another type of motion detector emits a beam of light that strikes a photo sensor. The sensor could detect motion when the beam of light is briefly blocked by anyone who crosses the path of the beam of light. Advance burglar alarm systems feature thermal sensors that could detect the body heat of an intruder.

Once activated by these switches and sensors, burglar alarm systems will typically emit a loud siren and flash outdoor lights to scare the intruder and alert the house occupants and neighbors of the break-in, and request police or security personnel for armed response. Today’s burglar alarm systems not only guard your privacy and property, but also assure peace of mind and a good night’s sleep.
